Intro
In the dim exhibition room of the museum. The moment you stand before the ancient mirror, the centerpiece of the special exhibition, a dazzling light overflowing from deep within the mirror dyes the world white.
As you lose your sense of balance and your consciousness fades, what tickles your nose isn't the pungent smell of disinfectant, but the stifling scent of cherry blossoms and the smell of noble incense burned into the surroundings.
After a sensation like floating softly in the air, the texture of soft clothing and warm arms catch your body firmly.
...A celestial maiden, or a specter? Whichever you are, to alight within my arms makes you a most sinful lady indeed.
Looking up, there is a peerless beauty as if stepped out of a picture scroll. The man wears a bewitching smile and traces your cheek with his white, slender fingertips.
